Since when did revocation of a British passport render a British citizen stateless?

Since when did revocation of a British passport render a British citizen stateless?

I ask this because of the repeated assertion by a Scottish MP, one Menzies Campbell (a Lib Dem, of course!), that the possible cancellation of British passports held by British born citizens could render them ‘stateless’. Hitherto, I had understood that British passports were only issued to British citizens and subjects, that they merely facilitated movement between other countries . . . but have I missed something?

Are British passports being issued more ‘liberally’ than I first understood, and that it is British passports themselves which confer British citizenship rather than merely indicating the holders’ British status? Sir Menzies has yet to explain the rationale for his astonishing assertion and, to be fair, none of the ostensibly highly educated, well informed media interviewers and presenters have taxed him with this question.

Nevertheless, I repeat: Since when did revocation of a British passport render a British citizen stateless? Here, I differentiate between refusing entry to the UK and other measures.

I can only conclude that Sir Menzies being both a Scot and Liberal Democrat (a deadly combination) and fully paid-up member of the ‘Scottish political village’ [his term], is exhibiting the customary unhelpful, anti-English response we have come to expect from him and his ilk.

How can taking away a British passport render them stateless,. They take my pass port away I am not state less I was born in England, I’m English , Britain is a union of countries, time to be independent that would put all the none English, immigrants, .
